order by refers to "wrong" tuple variable

[fehrenbach]

query {
 for (v <-- versions)
 orderby (v.id)
   [(id=v.id)]
}

compiles to

select (t1635."id") as "id",
       (t1634."id") as "order_1" -- <-- t1634 is not bound!
from TEST_version as t1635
order by order_1

Not sure what the resulting query is meant to be, but probably s/t1634/t1635/g.
Might or might not be related to #11.
